Application filed July 6, 1916. Serial No. 107,741.

To all vwhom t may concern: Be it known that I, PHILIP y C. RAGOTZKY, a citizen of the Unitedr States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania,y have invented a new and useful Improvement in Devices for Connecting Outside Vires toBuildings, of

rwhich the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form. a part of this specification.

The object of my invention is to provide a newand improved means for connecting telephone wires from poles to buildings.

As is well known, a telephone wire is now strung from a pole to porcelain 1ni sulators or knobs aiixedto the outer wall of the building, whence the wire is carried alongsuch outer wall to one or more other arm must be secured, by at least two screws,

insulators located at the point or points at` which the wire enters the house.4 The pole is usually located at some distance from the house, perhaps `directly opposite thereto, but more usually angularly opposite thereto. The ordinary porcelain insulator is of cylindrical shape provided with a central axial orifice and circumferential grooves; It is obvious that the insulator on thev building which makes direct con-r nection with the pole must be erected in a vertical position owing to the location of the point ou ther pole from which the wire is carried. From this insulator the wire is strung to a secondr insulator located in a horizontal position and screwed direct to the wall. Thence the wire passes to one or more othery insulators' from which the wire is carried into the interior of the building. The vertically positioned insulator which is directly connected with the cannot, of course, be secured directto the building wall, as if so attached its grooves would not be properly positioned to receive the wire; but the insulator is secured to one arm of an i.shaped bracket, whose other tothe wail. The erection of this bracket A and insulator involves some expense, partly due to the cost of the same,r but principally f arising from the value of the labor and time involvedintheir erection and in the tying of the wire thereto.

The object of my invention is tor dispense with the necessity of erecting this bracket and extra insulator and to make possible the pole aan

attachment of the wire leading from the pole direct to an insulator which may be substituted for the one which is now conneted to the bracket-supported insulator. To this end I have provided a new and improved construction of knob orinsu'lator which may be secured direct to the building walland-may be positioned indifferent Ways so that the circumferential grooves therein may be so positioned relative to the Wire from the pole as to permit such wire to be attached directly thereto.

Embodiinents of my invention are shown in the accompanying drawings, in which- Figure l isa plan view 'of a. knob embodying .my invention; Fig. 2 is a sectional view ofthe same; 3 is an elevation of the same; Fig. LL is a diagrammatic plan view showing the mode of operation ofthe invention:r and F ig. 5 is a. sectional view of a modification.

The insulator c, in its preferred form,

differs from an ordinary insulator in they following respects: Its end faces extend in planes at an oblique angle to its circum-v ferential wall. Its central hole d connecting its end faces extends atan oblique angle vto its circumferential wall but perpendicularly to its end walls. These features are not, in

their entirety, essential, -as will be pointedl out hereinafter, but they are desirable, and are deemed to be necessary to accomplish the very best results.

It will be obvious that whatever) be the location of the point on the pole a. from which the wire is strung, the insulator can be so positioned that the circumferential grooves Ir will extend in planes more or less nearly coincident with the direction of extension of the wire from the pole, so as to admit of such wire being directly attached thereto, While at the same time permitting the wire from the insulator to be led direct to one or more otherfinsulators, as heretofore, from Which'the wire is led to the interior of the building. It is also obvious that if the wire from the poleleads downwardly toward (say) a one-story buildino', the insulator may be adjusted to readily adapt itself for direct connection more eiiciently than if it were erectedin a vertical position on a bracket; f

The insulator is attachable directly to the y iii;

thereto7 namely, by means of an ordinary screw (not shown) extending through the hole d.

It is not essential that both end faces of the insulator shell extend at an"obliqne angle to its circumferential wall, but only that the end face which is applied to the well shall so extend. Thus, the opposite end fece may extend in a plane lat a rightengle to the circumferential wall, as indicated at in Fig. This eonstruetioii, however, is not desirable, because the connytersink for thescrew head must he made relatively large and also relatively close to the circumferential wall.

it is preferred to provide two sets of insulators, one set in which the angle oi inclination oi' the peripheral `wall to the end face is degrees andanother set in which such angle is 15 degrees; 'ont it will he nnderstood that the angle oi' inclination may be varied as described.

It will he appreciated that` hy reason o the capacity of my improvement to receive the Wire properly at varying angles, the strain or tension on the wire is reduced to a minimum.

llhere, in the claims, 'l specify a knol) i (do not mean to loe confined to e knob made miami of a single piece except Where expressly stated.

Haring now fully described my iiiven` tion what claim and desire to protect by Letters Patent is l. :i device Yfor attachment to buildings to permit of the direct connection thereto oi exterior wires, comprising e circumferentizilly grooved knob having one end face extending at an oblique angle to the longitudinal direction of extension of the circular grooved ieee und provided with ai] vorificeextending between the end faces, "and perpeni'licnlar to the ohliquely extending eiid face.
